GANG-PLOW.

Specificetion of Letters Patent.

Patented Dec. 26, 1911.

Application filed May 23, 1910. Seztial No. 562,812.

To all wlwm 'it may concern;

Be it known that I, ALBnn'r A. ALLEMAND, a citizen of the United States,residing at Gilroy, in the onnty of Santa Clara and State of California,have invented certain new and useful Improvements in Gang- Plows, ofwhich the following is a specification.

My invention relates to the class of gangplows of relatively large andheavy construction intended to be drawn by engines.

The object of my invention is to provide a plow of this class especiallyadapted for breaking up or dry-plowing hard soils, and to this end tconsists in the novel heavy construction of the frame, and thearrangenient 'and location of its wheels, as I shall now fully describeby reference to the accompanying drawings in which- Fignre 1 is a planof my plow. Fig. 2 is a side elevationof the same. Fig. 3 s a detail ofthe Steering wheel and its connections.

The beams 1 which may be in any number according to the size of theplow, are here shown as eight, and each beam is conposed of two parallclbars of steel set up odgewise, the bars of said beams receiving betweenthem the standards '2 of the plow-bodies 3, thus making a heavy rigidbeam. The beams are braced and held in position at the required distanceapart by heavy cast steel connecting braces 4 of I-shape, boltcd to thebeams, there being two braces be-` tween each beam, those braces at therear being opposite the plow standards 2, and their bolts serving tohold said standards in the beams. This makes a strong frame, and saidframe is further stitl'ened and reinforced by three trnss-braccs 5 eachtrnssbrace being conposed of parallel separated steel bars, whichreceive between them the bolts 6 passing down between the beam members,whereby said' braces and bearns are secnred together. One of these trnssbraces 5 is placed at the rear of the plow; another is located just infront of the standards 2 -and the third is located 'at the for- Wardends of the second and seventh bcams. These beans as will be seen, donot reach the head of the plow. 7 are the wheels.

The head of the plow frame is conposed of two stecl bars 8, laid flat,one on top and one under'the ends of the beams, said head bars beingsecured to the beams by the yokes 9. The wheels 7 are in pairs, the

members of each pair being nounted on an axle 10, which is centrallyconnected by a forked casting 11, with a vertical s indle 12, which isswiveled and slidable in t e frame, through the bearings 13. The draftbar 14 by which the low is drawn is -connected with the outer eams bymeans of irons15 depending from said beams and b'aced back by arms 16,and from these irons, chains 17 extend to the ulling bar. The draft baris also connecte with the wheels 7, by means of short, poles 18preferably made of fiat bars extending from the axles of said wheels.The connection of these poles With the draft bar is a sliding one,formed by slots 18' and bolts, so that there will be no cramping in theSteering operation. Said connection is also a yielding one, formcd bythe spring 7' and its connecting rods.

As will be seen, the wheels 7 are placed within the frame borders, onepair ahead of the second beam and the other pair ahead of the seventhhean, and by the pivoted noanting of said wheels the plow may be turnedwith faeility in either direction without danger of breaking the wheelsor npsetting the plow. This featnre of being able to trn in eitherdircction is a great .advantage in plowing land which is cut ug bydrainage ditches, as one can always bac frrow and throw the land awayfrom the diteh, thereby raising the land between the ditches andfacilitating the drainage. The advantage of having the wheels within theborders of the plow frame is that both sets rnn on the hard, relativelysmooth land, rather than in the fnrrow into which the clods or largelnmps always fall back and raise the plow ont of the gronnd;`bnt withthe whcelsas shown, the plow runs along snoothly and at the same depthalways leaving the sub-soil perfectly smooth, which is one of thegreatest advantagcs in the matter of drainage. By having the wheels inpairs a better bearing on the gronnd and a better support for the frameare afforded.

The standards of the plows are made heavy and tall, to give the plowplenty of clearanec which is a great necessity in dry 'plowing landwhich breaks np in large chnks. The plow is raised and lowered by twolevers 19, which are connccted by links 20 to the front of the plowframe, and which flcrn directly on the tops of the Wheel spidles 12.These levers engage racks 21 in the usual manner.

Having ths described my invention, what, I clain as new and desire tosecnre by Letters Patent is- 1. A gnng-plow comprising a 'frame havingelongated oppositeiy disposed side borders extending snhstnntinlly n'zdtet to the line of druft, a series of ptnw bndies carried by the.frame :it its rear portion, thse plow-hodies tnrning the ter ninnls ofthe series being in line with the side hm'ders of sid frame, sp mrting;wheels for the front of the. phw t'rnne hented near 'neh side hnt withinsaid side liinits of the pton hodies :it the side hnrders of the frane ndraft bar extenditransre'setr to the line of drntt :nd snhstnntizdlyfrom side tu Side of the naehine and 'enrwardly prnjeeting poles onendjzn-ent eneh end of the, drft hn' conneet'ed nt their renr ends one tothe axte of each wheet.
